Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497894, here are decompositions:

  • 5 + 2147497889 = 2147497894
  • 137 + 2147497757 = 2147497894
  • 197 + 2147497697 = 2147497894
  • 233 + 2147497661 = 2147497894
  • 401 + 2147497493 = 2147497894
  • 491 + 2147497403 = 2147497894
  • 761 + 2147497133 = 2147497894
  • 953 + 2147496941 = 2147497894

Showing the first eight; more decompositions exist.
